FIG. 2 is a side view thereof; and

FIG. 4 is an enlarged view of the claimed region in FIG. 2, shown in isolation.

The broken lines immediately adjacent to the shaded area represent unclaimed boundaries of the design. The seventeen unshaded regions within the shaded area, including the eight unshaded regions demarcated by broken lines, form no part of the claimed design. The broken lines showing the remainder of the shoe are for environmental purposes only and form no part of the claimed design.
